Preheat oven to 350 degrees
Combine butter and vanilla in a mixing bowl until smooth (I used my mixer with the paddle attachment)
Add 1/2 cup of the powdered — My daughter loved that she could do this herself
Slowly pour in the flour until well mixed, followed by the walnuts or pecans
Roll dough into 1-inch balls and place on a cookie sheet — Another great activity for the kiddo!
Bake 12-15 minutes or until lightly browned — careful the bottom doesn't burn!
Let cool for 2-3 minutes
Pour remaining powdered sugar on a plate then roll the cooled cake drops in the plate of sugar about 1-2 times each
Enjoy!
